Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Mitsubishi Diamante Owner Comments

problem #1

Oct 312003

Diamante 6-cyl

  • Automatic transmission
  • 773 miles


2003 Diamante purchased in Oct 2003. Vehicle vibrated "horribly" when brakes are applied. Vibration/loud highway tire noise. Both rear tires "cup". also, rubbing sound R/F wheel area when turning. Despite seven (7) attempts at repair by dealer this condition persists. Ongoing condition. Manufacturing rep offers to put on third new set of tires in 30K miles; yet states there is nothing wrong with the vehicle. Dealer's service dept acknowledges problems with brakes on Diamantes. We have been forced to employ an attorney to go the route of invoking the nc lemon law.
